BOTTLE-TOP.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed February 1, 1907. Serial No. 355,182.

To all whom it may concern:

Be'it known that 1, WILLIAM S. AYLING, a citizen of the United States, residing at Chicago, in the county of Cook and State of ,Illinois, have invented new and useful Improvements in Bottle-Tops, of which the following is a specification.

This invention relates to bottles, being especially directed to an attachment for closing the mouth of the bottle after the cork'has been extracted and embodies in its organization a tubular valve controlled .neckextension piece or section, together with a coupling member for detachably securing said extension in place on the bottle neck.

The invention has for its objects to provide a comparatively simple, inexpensive device of this character which may be readily installed for use, one whereby the bottle mouth will be maintained in closed condition to obviate the entrance of impurities into the bottle, one whereby the ordinary form of cork, after being once extracted, may be dispensed with, and one which, after the bottle has been emptied, may be readily disconnected and preserved for future use.

With these and other objects in view, the invention comprises the novel features of construction and combination of parts more fully hereinafter described in the accompanying drawings, Figure l is a side elevation of a portion of a bottle neck equipped with an attachment embodying the invention. Fig. 2 is a central longitudinal section taken on the line 22 of Fig. 1. Fig. 3 is a View in elevation of theextension piece or section. Fig. 4 is a detail cross-section taken on the line 4-4 of Fig. 2. Fig. 5 is a detail perspective view oi the valve-retaining member.

Referring to the drawings, 1 designates a bottle neck of the usual form and material having a central passage or bore 2 and provided at its upper end with a conical tapered enlargement 3 terminating at its lower end in a marginal shoulder 4.

Formed to seat on the upper end or mouth of the neck l is a tubular extension-piece or section 5 having a. central passage or bore 6 adapted to form a continuation of the passage 2 and reduced at its lower end to form a seat 7 on which normally rests a spherical or ball valve 8, there being formed marginally around the inner face of the section 5 and at a point above the valve 8, a groove or channel 9 designed to receive a valve-retaining member 10 composed oi wire and preferably in the form of a split ring having one of its ends bent to form a portion or linger 11 extended into and transversely of the ring.

The section 5, which has its lower end formed to fit in the upper end of the neck 1, is provided near its lower end with a marginal groove or recess 12 and with a marginal bead or rib 13 arranged at a point immediately below the groove 12, the section being removably secured in place by means of a coupling member or sleeve 14 composed of rubber or other suitable elastic material and having at its lower end an inturned portion or flange 15 formed to engage and fit beneath the shoulder 4 and at its upper end an inturned engaging portion or bead 16 adapted to enter the groove 12 and made of a shape in cross-section to properly fit within the latter, while formed on the interior of the coupling member which is internally tapered to conform to the enlargement 3, is a marginal groove or recess 17 adapted to receive the head or rib 13.

In practice, after the cork or other stopper has been extracted from the neck 1, the extension section 5 having the valve 8 arranged therein, is seated upon the upper end or mouth of the neck and coupled to the latter by means of the coupling member 4 in the manner which is obvious, it being understood that after the valve 8 has been entered into the section 5, the retaining member 10 is introduced into the bore 6 and sprung into the groove 9. It is apparent that when the valve extension is in place on the neck, the latter will be effectually closed except during the operation of decanting the liquid, and further that the coupling member 14 which, owing to its elasticity, may be readily introduced over the enlargement 3, will serve to maintain the extension in propel position but permits convenient disconnection of the parts after the bottle has been emptied and to permit of the extension being preserved for re-use.

Having thus described the invention, what I claim is:

l. A bottle neck provided with an external shoulder, a tubular extension seated on the upper end of the neck and provided with an external shoulder, a coupling member formed to fit on the upper portion of the neck and having end flanges to engage respectively with said shoulders for detachably securing the extension in place, and a movable valve arranged in the extension.

:2. A bottle neck provided with an external shoulder, a tubular extension seated on the neck and provided between its ends with an external shoulder, an elastic coupling sleeve fitted on the upper portion of the neck and provided with flanges to engage said shoulders for detachahly securing the extension in place, and a movable valve arranged in the extension.

3. A bottle neck, a tubular extension seated on the mouth of said neck, a movable valve arranged in the extension, and an elastic member fitted over the outside of the neck and engaging the extension to form a retainer for detuchably securing the latter in position on the neck.

In testimony whereof, I afiix my signature in presence of two witnesses.

WILLIAM S. AYLING.
